Participants will be asked to remain in the study for up to five years so that the investigators can document and evaluate long-term treatment outcome. Participants will meet with their STEP-BD psychiatrist for periodic evaluations and/or treatment adjustments during the course of the study, fill out various self-rating forms, and when applicable, participate in psychotherapy. One of the psychotherapy options, Family-Focused Therapy, will require participants and their families to attend counseling sessions together. Overall, the estimated amount of time required from participants in the study is 2 to 4 hours per month.
